Thank you for your input and suggestion.

>No harm in trying :-}
>Just make a note of any existing setting for the DNS server and go back to that if ness.
>OTOH, since it works using the IP address for testing you could stick with that....

>>Thank you for the link. However, until I understand any ramifications of making a change on iPad, I won't do it. I am sure you understand.

>>>>>>>Hi,
>>>>>>>
>>>>>>>I am trying to connect (load main page) an asp.net application running on one computer on a wi-fi network from iPad.
>>>>>>>
>>>>>>>Some background information. I can access this asp.net app from another PC in the office (entering in the browser http://PcServerName/AppName/MainPage.aspx) This works. The PCs as well as iPad use the same router. In fact if I enter in the Safari on iPad address 192.168.0.1 I get the login screen to the router. But when I enter in iPad address I get message that the server cannot be found.

>>>>>>>Does the above mean that something is not setup on iPad or on the PC hosting the application?

>>>>>>>TIA.

>>>>>>Can you use the IP of the webserver instead of the server name? Sounds like the iPad is not using your local DNS (if there is local DNS).

>>>>>I am always confused about the 'local DNS'. But I will run ipconfig on the PC where the application is running and try to access the application using IP instead of the server name. This is how I understand the url will change:

>>>>>Thank you.

>>>>>UPDATE: Success!

>>>>I'm not familiar with the iPad or how to configure networking for it. My guess is somehow you need to tell it to use your router's IP address as a DNS server so it will get information on server and PC names on your network.
